MEANS AND METHOD rota rnonncrne i Application filed March 7 Ourinvention relates to improvements in methods and means or producingruled ill printing forms and has special reference to improved means andmethods for producing suitably spaced openings in printing ornonprintingrules or members for properly holding and spacing what arecalled vertical rules in tabular matter, especially where the form ismade up otline printing members or type slugs.

A's horizontal ruling members are common- 1y made for interpositionbetween printing strips or slugs, they are type high andusual ly, itthey are thicker than two points, they have a shoulder which is .043 ofan inch below the top of the printing surface. Rising above thisshoulder is a V-shaped printing part, and in the method herein involvedthis upper part is perforated by V-shaped openings having overhangingside walls for receiving and retainingvertical ruling memhers of asimilar triangular shaped crosssection. This present invention has to dowith the production of these rule receiving openings, a number at a timeand in properly spaced relation to match or register with the tabularmatter being composed.

Many features of importance relate to structural and adjustment means bywhich we are enabled to readily assemble a series of independent punchesin a desired relation, and to simultaneously operate the punches, alsoto set a horizontal rule or dash slug in relation to the assembledpunches "for opertion thereon. Other features relate to the constructionand manipulation of the individual punch units, the construction of themachine for the convenient assembly therein of the punches and theirsimultaneous and proper manipulation.

l-Ve havev also devised a simple means of spacing the individual punchunits in the machine for producing properly spaced rule holding openingsin cross or horizontal dash slugs to properly cooperate with theprepared printing type slugs.

Further i'eatures 0t importance will ,be

In said drawings 1 illustratesa rectangular base to which upwardlyprojecting posts 2 and 3 are rigidly secured,one at each end, andadjacent to'the rear edge of the base. These posts are secured by screws4. The upper parts of these posts are offset inwardly, as shown at 5,and rest at these points upon afinished top surface 6 of the base. Theopposed faces 7 of these posts are holding projection shown in verticaland parallel with each other and are coincident with similar surfaces ,8on the base '1 beneath the posts 2 and 3. Between the opposed surfaces77 and 8 8 the various operating parts of the machine are mounted.

ber 9, secured to the base 1 by screws 10 and having a rear edge-11against which the punch units 12 are clampedto hold them in perfectalignment during the punching operations. v y V For thus clampmgthepunching units we provide a clamping member 13, having a lon-This'surfacefi is defined at its front gitudinal jaw 14 opposed totheclamping member 9. The member 18 is pivotally mounted at its endsbetween the surfaces 8 upon pivots 15 to swing back and forth so as i tomove the jaw llf'I'Oln and tow'ardthe o r posite member 9 to release andclamp the punch units 12. For swinging the member 13 we provide it witharm 16 which extends forwardly beneath the top of the base and carrieson its forward end a cam member 17 mounted on a horizontal bearing pin18 Se cured rigidly-in the free end of the arm 16. Thecam member 17 isrotatable on the pin 18 and has an eccentric cam surface 19 which can beturned into engagement'witli the under surface of the top of the base 1to depress the free end of the arm 16 and causethe clamping jaw 14 toswing toward the opposite clamping member 9. Normally the clamping jawsare held separated by a tension spring 20 connected at its lower end tothe arm 16 and atits upper end to the base 1. The cam member 17 is cutaway on the side opposite to the cam part 19,'as shown at 21, topermitthe arm to rise sufiiciently to cause the proper spreading of the jaws9'and 1 1.

Between the surfaces 7 of the posts sand 3 a second longitudinal member22 is. ar-

ranged, and extending from post to post.

This member is the punch operator and is mounted to swing on ahorizontal axis, its

front part beingadapted to swing up and down to operate the punches, itis provided with forwardly extending rigidly projecting handles or leverarms '23, one at each end, by which it can be easily operated. Theoperator is mounted on a bearing rod 2 1- which extends through theposts' 2 and 3 and the ends of which are supported in bearing members 25at one end 26 at the other end, which have innerjbearing ends 27ro-tatably mounted in bearing'openings 2S provided int-he posts 2' and3. The ends of the rod 2 1 are eccentrn ca-lly mounted in the bearingmembers, as shown inrthe several figures, and are rigidly connectedthereto to rotate therewith. 'One of said bearing members25 is providedon its outer'end with a knurled head 29 by'which the bearing members andthe rod 24 can be rotated. The rotation of the rod 2-'l-uis lini-' itedto 180 by a pin 31 rigidly projecting from the outer end 32 of thebearing member 26 and which contacts with suitable stops 33' on the post3. By rotating the rod 2 1 with its eccentric bearing members 25 and 26the operator 22 is moved bodily back andforth; this for engaging anddisengaging the punches, as will be more fully described hereinafter. vi

While the stops 33 prevent the rod being rotated too farin eitherdirection, we proviee accurate setting means for the members 2526. Thisconsists of a ball 34 and a. spring 35 carried in an opening 36 providedin the post 3 which carries the bearing memwith two ball receivingdepressions 37 into ber 25, and the bearing'member is provided which theball is forced by the spring. These depressions are accurately placed toproperly set the rotatable. member. comprising the rod 24 and theeccentric bearing members. The operator 22 is rotatably mounted on therod 24 and can swing up and down with the bearing members in eitherlimiting position. When the operator is moved forward it is in punchoperating position, and when moved back it is free of the punches andcan be swung up so that the handles. extend substantially vertically, asshown indotted linesin Figure 8.

jections 4 1 separated by blank spaces-or sur-' faces 42. These blankmatrices can be of uniform thickness and we preferably make the punchunits 12, which each comprise a suitable punch carrier or housing 43 anda punch member 44, of equal thickness with the blank matrices so that,as shown in Figures 26 and 27, the punch units 12 can be substituted forthe blank matrices in the assembled line of matrices, and the housingswill be spaced in accordance with the spacing of the blank matrices 39.Each housing 43 has a lower end which fits between the fixed abutment 11and theclampingmember 14, and at the forward edge of the housing it isprovided with a longitudinal guide opening 45 for containing the punch44. The punch unit is of a height to seat upon the flat surface G'of thebase, and atthe height of the top surface-oi the guide bar 9 itisprovided with "a notch 46 which is equal in depth to the usual heightof printing characters on lino-type slugs, such. as the proiections 41,above the blank spaces 42, VlZ, 43 thousandths of an inch. Above thisnotch the front edge of the housing projects forward to form a shoulderor surface 47 which is exactly .043 of an inch above the bottom of thenotch 46. This surface 47 extends up along the housing a short distance,and above this point the housing pro ects stll'l further forward toprovide the punch guide opening 45.

ed ges 49 at thesides of the slot can be formed in toward each-other, asshown in. full lines, Figure 5, to close the front edge of theslot andcomplete the guide opening The On many type slug casting machines of'along one side of its upper edge.

are free of the operator, so that the ope bottom 50 of the slotisV-shaped to receive he V-shaped rear edge 51 of the punch 44.

The rules 53, as shown in. Figure 14, which are designed to he iirertedinto and held in the openings produced by the punchcs44,

are triangularin cross-section, having a flat base 54 and a more or lesssharp top printing edge 55, depending on the kind of line, that is to beprinted. These rules are .043 of an inch in height and are adapted torest on the blank tops of lino-type and similar sings with theirprinting edges 55 in the top printing plane of the type form, as bestindicated in Figure 29. The punches are formed to produce the triangularopenings in the upper edges of ruling members for receiving these rules.

'lrinting rules are ofseveral kinds as to shape, size, etc, and we haveillustrated two typical forms. One form, as shown in Figure 13 at 57,hasa relatively thin body 58 and also a relatively thin printing portion59 The portion 59 rises from a iiat'top surface 60 which is .043 of an.inch below the printing surface and is coincident as to height with theblank surfaces 42 on the printing slugs, and the bot toms of the ruleopenings 56 are coincident with this surfaceQGO. The rule 57 has theprinting strip 5.) arranged coincident with one ilat side of the'r-uleand usually con stituteswhat is known as a hair line rule. The othertypical rule 61, shown in Figure 15, has a printing rib 62 arrangedsubstantially along the center of the flat top 68 of the ruleinstead ofalong one edge. Our n'iachine is arranged for punching the rulereceiving openings 56 in both these styles of rules and for properlygauging the. depths of these openings from the pri nting faces of therules.

The punches 44 are each formed of a flat strip of metal, preferablyequal. in thickness to the width of the base of the ti-shaped edge 51and V tireferably about three times the height of said t -shaped edgeportion in width, provided with a body portion (34 ex tendinglongitudinally of the Vshaped edge. The body portion is cut away at thelower end, leaving the lower end 6511f the t -shaped edge projectingfreely to st ve as the punch proper. The upper end of the punch-n11ember projects'above the housing and providcd with a rearwardlyextending projection. 66 adapted for cngagemcntby the punch operator 22and below this projection with a .StOP projection. 67 adapted to contactwith the upperend of the housing 12 and limit the downward movement ofthe punch. The particular function or the stop 6'? is to hold theseveral punches with their projections (56 in-horizontalalignment whenthe punches ttor can he engaged'with them. in manner to be described.The edge of theV-shaped punch ice is coincident with the bottom surface68 of the notch 46, andthe .bottom surface 69 of the V-shaped punch endis coincident with the tion of the ribs 59 and 62 on the ruling members57 and 61. The top of the rule support 9 which extends along in front ofthepunches and upon which the ruling members are laid thus properlyaligning the rules for punch- For arranging the device to punch. rulesing.

' like that shown in Figure 15, that is, rules in which the rib is notcoincident with one side of the rule, there is provided a removable topstrip 71 on the rule support 9 which can be taken off, thus providing alower supporting surface for the slug which has the rule holdingprojection set in from a side face and causing the projection or rib 62to properly register with the notches 4G.

In order that a punch may be enabled to cut a hole in a member beingpunched it is necessary that a die opening be provided,

,into which the cutting end of the punch is projected in the punchingoperation. The production of the relatively small die openings for usein producing the small triangular openings, for the vertical rules 53,has been a problem, and it is almost an impossibility to produce suchopenings in the solid metal. We have succeeded in simplifying theproduction of such die openings by the following simple construction.The front edge 43 of the punch holder, below the notch 46, terminates ina vertical flat surface 47 coincident with the front surface 4-7 abovethe notch 46 and also coincident with base of the triangular punch end65, and in clamping the punch units in place in the machine this surface47 is clamped tightly against the rear edge of the supporting strip 9.The strip 9 therefore forms the third side of the triangular dieopening.It is relatively easy to cut the V-groove in the die holder in which thepunch tit and. operates, as this is done with a-suitable milling cutter,and when this notch is closed by the supporting strip 9 the die openingis completed and all the corners of the opening can thus readily andcheaply be made perfect. i

In making up some tabular forms rule holding members 72 similar to themember 61 are'made use of which have ribs 73 which do not rise to theprintingsurface, such a member-is shown in Figure 24. In

surfa 'e 4-7 of the housing. The lower end or surface of the notches ison a slight incline, approximating somewhat the inclinapunching thisform the-top flat surface 7 1:"

The memberis pushed in until this surface 7icontacts with the surface 1.? of thepunch, then as before the punches are-oper- Med and the notches out Anynumber of; the punch units 12 can be arranged in the. machine betweenthe posts 2 and 3. are set upright on the supporting surface 6 and areclamped tightly against the rear edge 11 of the plate or. bar 9 by theclamping member 13. The lower end of the rear edge of each housing isinclined outwardly, as shown at 75, Figure 16,and the engaging'sun faceof the clamp member 13 is likewise inclmed so that the action of theclamping mem her will be toforce the housings downwardly upon thesurface 6 and forwardly against the surface 11 forholding the housingsac curately in position. Below thenotch 46 each housing is provided withan extension 76 of the V-shaped openingor groove for receiving the pointof the punches; it descends. to the lower limit ofits movementandbelowthis point,'as shown at77, the groove or open-. ing is flared out toafford ample clearance for the chips cut out by; the'punch, andthe frameis provided with a longitudinal chip groove 7 8 and clearing holes'7 9may be provided through the base at intervals through which the chipscan fall out of themachine,

At the lower end of the forward. edge of the housings, each is providedwith a for wardly projecting toe 80 which is'adapted to enter a grooveprovided under the adjacent edge of the rule support 9; this is for thepur pose of preventing the housings being inadvertently pulled up evenif the clamping" member 13 should not be clamped tight. This groove isless in height than the toes 81' as ordinarily made on lino-typematrices 38 for a purpose to be described later. As well illustrated inthe drawings the punch units can be placed in any'desired spacing in themachine and We arrange the operator 22 so as to be readily engaged withthem and to be disengaged from them and swing outof the way to permit'oftheir being placed in and removed from the machine and arranged inany desired relation. r

, lVhen the punches are not engagedby the operator 22 they naturallydrop down; until the stop projections 67 on the punches rest on the topsof the housings, in which position each punch is at the lower limit ofits movement and this is the position of each of the punches before thepunch operator is brought into engagement with the punches.

Asshown in Figure 1, and as has been described, the punch units may bespaced by the matrices which were used inproducing the printing slugwith which'it is desired to use some rule-holding members, or obviouslythey can'be spaced in many other waysto c0rrespond with the tabular workwhich it is desired to produce. The punch units having been substitutedfor theblank matrices, as shown in Figure 27, the matrices and punchunits as an entity can be placed in the machine and clamped in position.In this use it is usually advisable, though not necessary, to clamp theseries of matrices and punch units together longitudinallyof themachine. For this purpose we provide an adjustable screw 82 projectingthrough the post 3 and in alignment with the punch units and blocks 83and 84 may be used to fill in between the post 2,-th-e screw 82 and theseries of matrices and punch units in an obvious manner. The head 85 ofthe screw 82 is provided with circumferential indications 86 for apurpose to be described.

Instead of making use of the matrices to space the punch units in themachine they may be used merely to space the units and then other meansmay be employed to retain the units in this spaced relation while beingtransferred into themachine. This other means may consist of a rod 87,the several housings being each provided with an opening 88 for this rodso that, as shown in Figure 27, the several housings can be strung alongon therod, or if the housings are already spaced, as bythe matrices, therod can be pushed through the severalhousings. Each housing is providedwith a set screw 89, preferably at its upper end for binding the housingto the rod. As-indicated in the drawings,

the set screw 89 may also be arranged at the rear edge of the housing.It is to be noted that the rod 87 is so placed that it is free of thematrices passing through the upper V shaped openings thereof. Preferablythe rod 87 is long enough to reach from post to post of the machine, andwe may provide an opening or notch 90 in the forward part of the post 2through which the rod could be en tered or withdrawn. This is forconvenience in making changes in the punch units without the necessityof removing them all from the machine. i i 7 We have illustrated otherconvenient ways of spacing the puncheson the rod 87. WVe may provide atrough men' ber 91 (Figure 25), having an inclinedrightangled trough 92for receiving the punch units. The bottom ends of the punch units areplaced against the side 93 of the trough. If the guide'for setting thepunches consists of a printed sheet havin lines on itto'be reproduced bythe tri- It is obvious that step is to place a rule on the machine for.

punching. It is sometimes necessary to punch a number of rules exactlysimilar one to the other for use in making up a form, and in any eventthe piece ofrule to be punched must be properly positionedlongitudinally of the row of punches so that the rule receivin openingsshall be properly placedrelatively'to' the ends of the rule; For thispurpose there is provided astop project-ion 97 secured on one end ofalongitudinally slidable bar 98 arr: nged infront of the slug rest 9 andguided bythe front edge 99 of same. The stop 97 projects overthe top oftheslug restin position to engage one end of a rule 100 laid on therest. The bar 98 is adapted to be clamped tightly in any adjustedposition by means of a centrally arranged clamp comprising ahooked plate101 and a clamping screw 102 operable in an obvious manner. Theprojection or abutment 97 is T-shaped so that the bar 98 can be reversedas to position to place the stop at the right hand instead of at theleft hand as show In adjusting the stop 97 any suitable means can beemployed, one such means being to lay centering indication. After theprinting slug has been thus set the bar 98 isadjusted to bringthe stopagainst the adjacent end of the slug and then the bar is secured by theclamp 101. Then the rule pieces to be punched can be properly registeredwith the punches by being placed in contact withthe stop 97. V V I It isto be noted that our machine is particularly adapted for punching rulereceiving openings in extralong strips such as that shown in dottedlines in Figure 1 at 100. For instance, if a printin form is being madeup even 24 wide the punches can be arranged and the stop 97 set forpunching onehalf the length of the strip, and then the stop 97 can hechanged to the other end of the machine and the punches arranged topunch the other end of the strip. 'lhisarrangement is made possiblekeeping the end posts 2 and 3 back out of the way so that there is freelUO space provided for the-overhanging parts-of the strip when one endis being punched.

, The next operation is to engage the punch operator 22 with the alignedpunches. The

' several movementsand positions of the punch operator are illustratedin Figures 6 to 11 in elusive. -As herembefore explained, the operatoris adaptedto be moved bodily forward and back and it can alsobe swung.up and down on the rod'Qt as a bearing by means of the handles; In theturning of the eccentric .bearings 26 and 27 through 180 from oneposition to the other the rod 24 is swung downbelow itslin'iitingpositions, and this swinging down hasian iinportantfunction in theengaging of thepunches51.

Thegedge of the operator which is presented to the punches is providedwith a' lon- .gitudinal groove 103 ofa height to receive theprojections. 66 at the upper ends of the punches 51. Normally when theoperator is engaged with the punches it holds them in raised positionwith their lower punching ends drawn up above the notches 46 and readyto' be depressed. to punch the rules. As the punches, when disengaged,are dropped down and normally, when engaged, are raised, it

is necessary to oause thc' groove 103 of the operator to register withthe pro ections in the beginning ofthe engaging movement and to raisethe punches as the engaging. operation is completed. Tonormally hold thefront edge of the operator raised there is a pull spring 104 whichextends between .the'rear edge of the'operator and the base and tends tohold {the operator with the front edge raised. This spring 'issoarranged that it only comes into operation when the operator is swungdown nearly to operative position.

As has been explained, the operator can be swung-up to aposition wherethe handles 28 stand substantially vertical and we arrange the spring sothat thisextreme movement can be had without cramping it. Thisarrangement consists in securing the lower end of the spring to a verreally swinging :link 1055. his link can swing freely down as theoperator is raised when the operator is swung down the link is lifteduntil stopped by a stop shoulder 106 onthe base, after which the springcomes into action. The upper end of the spring is hooked to the rearedge of the operator through the medium of a looped staple 107 securedto and projecting from the rear edge of the operator..

WVe arrange positive means for causing the operator to register withthepunches and the arrangement is such that assoon as the operator is en a'ed with the Junches sufficient to 1 b b a I lift them the spring-103operates to swingthe front, edge of the operator up and lift thepunches. This control of the operator con- 's'ists of a stop pinprojecting horizontally andlongitudinally of the operatorat its rightiand end and in the planeof the post 3. The

pin 108 isarranged near-therearedge-of the operator-that is on theopposite side offlthc operator from i the handles 23. 109 in Figure 8,the post 3 is cut-away below the bearing to vpermit it to swing down-andin when the operator is swung up toppermit the removal and placement ofthe punch 1 shown: at

The normal setting of the operator when in itsrearwardposition, shown in Figure 8, in which position the stop 108 isslightly belowthe stop surface 111 and slightly to the rear of therearedge 112 "of the'post 3. In horizontal aligninenttwith the stop 111vthere is provided a. recess 116 into which the stoppinr108 enters as-theeccentric bearings are rotated 130411010 the operator forwardintoeugagementwith the punches. The wall 112 is provided with-a rounded camsurface 11 1 which the pin 108 is adapted. to engage as the operator ismoved forward. This cam surface forces the pin up and consequently theforward edge of the operator down against the action, of the spring 104and the bottoniwall 115 of the recess 113 is so arranged that as theoperator isinoved forward the groove 103 isbrought to register witlr theprojections 06 on' the punches. It will be understood that this actionis caused by the swinging downwardly of the bearing rod 24 in the;rotation of the eccentric bearing members during the first half of suchmovement. During the latter half of such movement the .bearing rod israised and the forward edge of the operator rises, due to the pull ofthe spring 104 thus, 7

lifting the punches to their upper positions.

To permit the operatorto be swung down freely when in its forwardposition the recess 113 has an upward extension 116 at itsiinner *endpermitting the stop 108' to swing up ,a

limited distance when the operatoris depressed to punch the rules. Thelimitation in this last movement by the step 108 is sufficient toprevent any undue strain on-the stop projections 67 of the punches.

- Sometimes it is desirable to move the whole series of punches along inthe machine aeertaindefinite amount in printersme-asure, and

.forthis purpose the screw 82 hasia certain pitch so that eachrevolution of the screw,

will move it bodily longitudinally a certain distance, such forinstance,-the screw is preferably made with 24 threads per inch and theI 7 This is of advantage in making up some forms where rules are desiredspaced from each other, as in the production of pairs of parallel lines.

Tn'Figures to 37 we. have illustrated a means for providin the ruleholding openings where it is impossible or undesirable to provide oruse. fullheight members, such as the rules 57 or non-printing members72, which are full height and arranged between other full heightmembers. To meet this sitnation we provide projections 117 on the topsurface of a printing slug 118 in the blank spaces between-theprintingcharacters 119.

These projections are cast solid, that is, without rule holdingopenings, and are later punched inthe machine similar to the punching ofthe holes in the other rule holding members. Preferably these ruleholding projections are snorter than the blan spaces upon which they arecast and are preferably arranged at one edge of the top of the slug so 7that they can be entered into the punches, as

beforeeXplained,with the top surface of the slug in contact with thesurfaces 47 of the punch holders. This is for the reason that theseprojections are not type high, as-then they would produce undesiredimpressions on the paper in printin As these projections are butslightly less than type high in order to afford a proper punches andavoid the deformation of the .upper edges of theprojections above men-.

tioned. r i

For producing such projections we provide matrices 122- of'the generalform used in such machines'for producing such slugs and provided with anotch 123 in its'operating edge of the proper shape to" produce theprojection I desired. That is, it .is preferably a V-shaped notchhavinga rounded pro ection or hump 124C in its bottom and of the propershape to.

produce the depression 121 in the projections 117. 1 7
